切换到root用户：su root
输入密码
备份文件：cp /etc/apt/sources.list /etc/apt/sources.list.bak
修改sources.list文件：vim /etc/apt/sources.list

在文件中加入如下的内容：

deb http://mirrors.sohu.com/ubuntu/ precise-updates main restricted
deb-src http://mirrors.sohu.com/ubuntu/ precise-updates main restricted
deb http://mirrors.sohu.com/ubuntu/ precise universe
deb-src http://mirrors.sohu.com/ubuntu/ precise universe
deb http://mirrors.sohu.com/ubuntu/ precise-updates universe

deb http://mirrors.sohu.com/ubuntu/ precise-backports main restricted universe multiverse
